“Any testing or observation of battery life to date by anyone outside of RIM would have been performed using pre-beta units that were built without power management implemented. RIM is on track with its schedule to optimize the BlackBerry PlayBook’s battery life and looks forward to providing customers with a professional grade tablet that offers superior performance with comparable battery life.”

Hopefully, the Kaufman Brother’s claim will prompt RIM to improve whatever battery life they initially planned after the Playbook’s power management is implemented.
